Yes.. cold air is much more efficient than warm engine bay air. This
has been a debate with watercooled inline 4 tuners for years. Keep in
mind.. you will never even notice the hp gains until you hit around
5000 rpm's and above with a "hogged out" air box anyway.. who drives
there vans at that rpm very often?
Cool air... K&N filter in the stock box.. that is always the way to go
unless your racing your van .. ha ha ha..
